ORS Plus Adverse Reactions

Hypernatraemia is characteristic of excessive (sodium) administration, including the overfeeding or inappropriate feeding of infants, in brain injury and acute water lack.
Symptoms of hypernatraemia may include restlessness, weakness, thirst, reduced salivation and lachrymation, swollen tongue, flushing of the skin, pyrexia, dizziness, headache, oliguria, hypotension, tachycardia, delirium, hyperpnea and respiratory arrest.
Retention of sodium and water - isotonic retention or iso-osmotic expansion because the plasma concentration in unchanged - leads to the accumulation of extracellular fluid (oedema). This may affect the cerebral, pulmonary, or peripheral circulation.
The toxicity of potassium salts by mouth in healthy individuals is slight, since potassium is rapidly excreted in the urine. With some salts, such as potassium chloride, nausea, vomiting, diarrhea and abdominal cramps may occur. Hyperkalaemia may occur after excessive intake (including the excessive transfusion of stored blood), after the use of potassium-sparing diuretics, in adrenal cortical insufficiency, renal failure, and acidosis and after tissue trauma. Symptoms include paraesthesia of the extremities, listlessness, mental confusion, weakness, paralysis, hypotension, cardiac arrhythmia, heart block, and cardiac arrest.
Concentrated glucose solutions given by mouth may cause nausea and vomiting.
